ISCH_PrimitivePolygon.reset() method

This API is provided as a beta preview for developers and may change based on feedback that we receive. Do not use this API in a production environment.

Reset the async primitive to the current canvas state

Signature

public reset(): Promise<ISCH_PrimitivePolygon>;

Returns

Promise<ISCH_PrimitivePolygon>

Polygon primitive object

Example

// 1. 生成本次运行专用的坐标，避免与之前保留的测试多边形重合
const x = 2000 + Math.floor(Math.random() * 8000);
const y = 2000 + Math.floor(Math.random() * 8000);
const line = [x, y, x + 400, y, x + 400, y + 300, x, y + 300];

// 2. 创建一个线宽 6 的测试多边形（SCH 坐标单位 10mil）
const polygon = await eda.sch_PrimitivePolygon.create(line, '#FF0000', null, 6, 0);

// 3. 切换异步模式，累计一处未提交的线宽修改（6 → 99）
const asyncPolygon = polygon.toAsync();
asyncPolygon.setState_LineWidth(99);

// 4. 重置：丢弃未提交的修改，回到画布当前状态
await asyncPolygon.reset();

// 5. 从画布重新读取，线宽仍是 6（保留现场供观察）
const refetched = await eda.sch_PrimitivePolygon.get(polygon.getState_PrimitiveId());

console.log('lineWidth after reset:', refetched.getState_LineWidth());
